Question about 1999 Ford Expedition
I'm having trouble with my 4x4 on my 2005 expedition the 4x4 low and high lights flash on the dash. to make a long story short the dealership I bought it from replaced a sensor but it's still not working and I contestant generality the idiots the dealership anymore. my brother thinks it might be the 4x4 axle actuator. I have an old 99 expedition so if I can use the actuator from that expedition I'd love to save the money on buying a new one but my brother isn't sure if I can. just looking for some help!

SOURCE: Stuck in 4 wheel drive high
I disconnected the electronic control on the transfer case and it seems to have unlocked the 4x4
At the back of the transfer case, near the top, there is a connector. I unplugged it and that seems to have disconnected the 4x4. My 2002 Explorer was stuck in 4x4, even though the 4x4 light was not on and I hit the Auto button a lot.

the 4x4 high light has been on far longer than the low ratio light, I suspect it has simply worn out and blown, try a new light. other than that the switch in the transmission could be faulty / have corroded connectors

Shown here is the P2104 obd2 code and their general meaning. For a brief description of any particular OBD2 code and how to fix the obd2 trouble code, please browsw below.
P2104 Engine TP Actuator Cntl System
This obd2 code is very common on newer vehicles which contain new design of throttle positioner sensor. Instead of putting a tps sensor at the side of your throttle body as in older engines, a throttle actuator control system is installed which eliminates the mechanical linkage (cable) between the throttle body and the throttle pedal. Under the throttle pedal, a throttle switch is installed and a throttle module or actuator is incorporated beside the throttle body. Because there is no mechanical device that wears out, it is more effecient in delivering better mileage and performance torque (besides...the actuator module performs better in getting all throttle signals to the ecm and trany).
To test this code, check the integrity of the wires going to both the throttle body actuator and the ecm including the throttle switch. Most of the time, if you have symptoms like trany going to a limp mode, the culprit originates from the trany circuit. However, if the symptom is engine related like hesitation, the problem resides in the throttle actuator itself which may sometimes includes the replacement of the whole throttle body assembly. Contact ATS if you need a wiring diagram or detailed fixes for your throttle actuator control system.
Before replacing the throttle control actuator and throttle body, try cleaning the throttle plates and all plug-in wiring connections. Also, watch out the throttle body mounting bolts which can easily break (use care) when removing them.

This is called the selector motor and you may be correct this is a common problem with these trucks the selector motor goes bad and will not engage the correct gear setting you select.
